Passive solar design and sunset views?

I failed a bit on the placement of the house on the site. Ideally all of your big window walls should be south facing to receive the least amount of sun light. Of course you'd want minimal windows facing east and west as they get direct sun in the morning and late afternoon. But we have the water and sunsets we wanted off our deck and so the sliders basically fall prey to the direct heat from the setting sun. As an attempt to counter this there is a 12ft roof which protects the silders up to a point then the sun gets its straight shot. All is not lost however. Because of the shade from both trees and the part of the house that sits out from the rest, the two big sliders that are the main living space in the house do not receive any of this sun (at least right now during the winter months). It is basically the 2 bedrooms that are effected. The Glide House Sunshade idea could be one option. From the Michele Kaufman website, "On warm days, keep the sunshades drawn and create a cross-breeze by opening the sliding glass doors and opposite clerestory windows (above the storage bars). This will cool the space while letting natural light in. On cooler days, open the exterior sunshades and keep the sliding doors and windows closed. This will allow the sun to heat the space while you enjoy the beautiful views!"
